Stripe, PayPal, and Square each have strengths for self-employed tradespeople – but choosing the wrong one can cost you more than just the transaction fees. Let's find the best fit for your roofing, plumbing, or flooring business.

The Quick Answer for Solo Tradesmen

Stripe is the right choice if you need professional online invoicing, want to accept deposits before a job starts, or plan to link payments directly with your accounting software. Square is built for taking payments on the job site – its mobile card readers and app make it easy to charge customers right after the work is done. PayPal makes sense if some customers specifically ask for it, or if you need a quick way to send an invoice for an unexpected repair without any hardware.

Side-by-Side Breakdown for Contractors

Stripe: Charges 2.9% + 30 cents for online transactions (like invoicing) and 2.7% + 5 cents for in-person payments with their hardware. No monthly fee for standard use. Strong for professional invoicing, recurring billing for maintenance contracts, and linking with accounting tools. They handle many currencies, useful if you source materials internationally.

PayPal: Charges 3.49% + 49 cents for standard online payments and 2.29% + 9 cents for in-person via PayPal Zettle. Works in over 200 countries and many currencies. Many customers recognize and trust the brand. Be aware: they are known for placing holds on accounts, which can be a problem if you have a large payment for a job or materials.

Square: Charges 2.6% + 10 cents for in-person payments with their reader and 2.9% + 30 cents for online invoices. You often get a free basic card reader when you sign up. Their system is excellent for managing estimates, invoices, and taking payments on your smartphone or tablet right there at the customer's house or job site.

When to Choose Stripe for Your Trade Business

Choose Stripe if you mostly send invoices to customers after the work is done, or if you need to take deposits for larger jobs (like a new roof or full bathroom remodel) before you even buy materials. It's excellent for creating professional online invoices that customers can pay directly with their credit card. If you use specialized accounting software for your trade business, Stripe often offers deeper connections, helping you keep your books tidy and track job costs automatically.

When to Choose Square for On-Site Payments

Square is your best bet if you need to take payment right away, directly on the job site. This is perfect for the end of a plumbing repair, after installing new flooring, or finishing a drywall patch. You can send estimates, convert them to invoices, and then swipe or tap the customer's card using a simple mobile reader connected to your phone or tablet. It's designed for mobile work, allowing you to manage your jobs, send invoices, and get paid quickly without needing an office.

When to Choose PayPal for Quick Invoicing

Consider PayPal if some of your customers specifically ask to pay that way because they trust the brand or have an existing PayPal account. It's also useful if you need to send a quick, no-fuss payment request for a small, unexpected repair or an extra part without having a card reader with you. You can send a payment link via text or email and get paid fast. However, for larger payments common in trades, be careful of PayPal's history of account holds, which could tie up your money.

The Verdict for Your Solo Trade Business

Start with Stripe if you need robust online invoicing and want to accept deposits for bigger jobs efficiently. Start with Square if you mainly get paid on the spot and need a reliable mobile card reader and invoicing app for your phone or tablet. Add PayPal as a secondary option only if your customers regularly ask for it. Do not rely on PayPal for your main income stream, especially for large payments, as their account hold risk is real and can stall your cash flow without warning.

How to Get Started with Payment Processing

Stripe: Go to stripe.com, create a business account, and verify your details. You can start sending online invoices and payment links the same day. Their payment links are great for deposits or final payments.

Square: Sign up at squareup.com. Order the free basic card reader (it plugs into your phone's headphone jack or connects via Bluetooth). Download the Square Point of Sale app to your smartphone or tablet. You can be taking in-person payments as soon as your hardware arrives, usually within a few days.

PayPal: Create a business account at paypal.com/business. You can immediately send payment requests via email or text. If you want a mobile card reader, look into PayPal Zettle, but be aware of the higher transaction fees compared to Square.

FREQUENTLY ASKED QUESTIONS

Can I use Stripe and PayPal together?

Yes. Many businesses use Stripe as the primary processor and add PayPal as a secondary option at checkout. This adds 5-15% additional conversion for customers who prefer PayPal. The trade-off is two separate payout schedules and two reconciliation streams.

Why do PayPal accounts get held?

PayPal holds funds when their fraud algorithms flag unusual activity — a sudden spike in volume, high-value transactions, or a spike in disputes. Holds can last 180 days in extreme cases. Stripe and Square also have hold policies, but they are generally less aggressive and more transparent about resolution.

What are interchange fees and do I pay them?

Interchange is the fee the card network charges the payment processor. With flat-rate pricing, you pay the listed rate and the processor absorbs variance. With interchange-plus pricing (available at higher volumes), you pay interchange directly plus a small markup — cheaper at scale.
